The working principle of the DC fan

The working principle of the DC fan:DC cooling fan is the use of electromagnetic induction principle,the use of hall sensor component as synchronous detection device,control a set of circuit,switching winding current order to produce a rotating magnetic field,realize electronic commutation electromechanical integration of the new type fan.Has a wide scope of speed control , controllability,reliability,light quality,environmental protection and energy saving,tolerance has obvious advantages in environment and economy,in the field of the requirement of high performance gradually take the place of other types of motors,dominant,mainly reflects in:

  1. long life, high reliability;
  2. High performance, stable operation;
  3. Intelligent, electromechanical integration, easy to control;
  4. Small volume, low power consumption;
  5. Low noise, no electromagnetic interference.
